In-Out: Elimination of first order bend, "In-Out bends", requires varying the thickness of the bracket base for individual teeth and placing attachments for molars at an angle to the buccal surface, so that molar rotation can be controlled automatically.

Tip: Tipping of the edgewise brackets is necessary to eliminate the second order bends. Allows for the compensation of the inclination of the incisal edge of the teeth relative to the long axis.

Torque: Cutting the bracket slot into the bracket at an angle, which is called "placing torque in the bracket", allows a horizontally flat rectangular arch wire to be placed into the bracket slots without incorporating twist bends.
